Hi Mark, Unfort. no experiences yet. But asfaik the datatype sizes of .NET are standardized. Thus an int will always be 32-bit, no matter if you run it on a 32 or 64 bit machine. Your app won't profit here. At least in theory you should be able to use a RAM based index > 2GB. I just see the problem of rebuilding the index each time your app goes down. Maybe an implementation leveraging memory-mapped files might be a good hybrid solution here. Let us know your experiences - I'm eager to hear about it cheers, Erich

We need to know if lucene.net is capable of running in a 64 bit environment and if being in a 64 bit environment will increase performance or will it just operate as 32 bit. Has anyone had experience with this type of deployment? Will this allow us to use ram instead of file system. Our index size is > 2 gigs. Thanks in advance Mark Burks
